This paper introduced a much more precise sampling method using CPU hardware performance counters (CHPC) to provide CPU data like instruction cycles, cache misses, branch prediction, and so on, and given detail scene of software status.

 
  • 摘要引入了基于CPU硬件性能計數器的性能數據采集和分析方法,從軟件運行時(shí)刻的細粒度參數入手分析軟件運行時(shí)刻的性能表現,從而更為準確地反映系統實(shí)際的動(dòng)態(tài)運行狀態(tài)。
